Sticking Gear Strut

Here's something I'll bet you've never seen before.

 

It only happened once (makes a big bang in the cockpit). Not related to any stress history on the gear, but rather appears to be related to storage and slightly low pressure, the aircraft hadn't been flown in a few months.

Yes, it was just once. After that flight we put it on jacks, checked everything, and topped off the nitrogen. The pressure was low which seems to have been a contributing factor. High pressure probably prevented much compression, hiding a production discrepancy in the strut. I've never (knock on wood) had an overfirm landing so those struts have probably never been fully compressed subsequent to delivery.

Yeah, I've seen that before. A buddy of mine bought an X up in West Virginia that had been sitting for a few years. Our team went up and did some repairs, got it back in annual and I flew it back to Tennessee for him. Right after I took off from Wheeling I heard that noise. I knew it had something to do with the gear (hoping one gear leg hadn't just fell off). The gear closed normally. So, I didn't think too much about it. Later, when we had it back in my shop an up on my jacks it did it again. His struts were low on nitrogen, too.
